Perhaps I'm speaking out of turn, but I have to wonder: am I the only one
who gets uncomfortable looking at these hacks to overload struct page? It
seems fragile as all hell; woe to he who tries to make a change to struct
page someday and has to track all of this stuff down.

Are the savings gained by using struct page this way really worth the
added complexity?
